Brad Bosch	6e9756ff79	HAL_PX4: Rework support for FLOW_CONTROL_AUTO. Now instead of requiring the buffer to fill completely before we can detect it is not draining, we use a time based mechanism to detect when none of the first few bytes are transmitted after sitting in our buffer a half second or more after flow control is enabled. This huristic is reliable only for the first several chracters because we believe that the radio must still have plenty of room in it's own buffers at that time even if it is not able to transmit them to the other radio yet. Note that the original algorithm made the same assumption. The new algorithm is especially helpful for cases where only keepalive messages are transmitted before other packets can be requested by the GCS. In this situation, the original code required almost 2 minutes to disable flow control and allow communication with the GCS.	10 years ago
Lucas De Marchi	83cfaf4a59	AP_HAL_PX4: standardize inclusion of libaries headers Do the missing header changes due to changing the code before the pr getting accepted.	10 years ago
Gustavo Jose de Sousa	08333f1ffe	AP_HAL_PX4: standardize inclusion of libaries headers This commit changes the way libraries headers are included in source files: - If the header is in the same directory the source belongs to, so the notation '#include ""' is used with the path relative to the directory containing the source. - If the header is outside the directory containing the source, then we use the notation '#include <>' with the path relative to libraries folder. Some of the advantages of such approach: - Only one search path for libraries headers. - OSs like Windows may have a better lookup time.	10 years ago

Andrew Tridgell	7cd7ff89fd	HAL_PX4: recover 12k of ram from USB buffers faster NuttX means we don't need such larger buffers	10 years ago
Jonathan Challinger	e908fcafb1	AP_HAL_PX4: attempt to initialize USB while soft-disarmed	10 years ago
Andrew Tridgell	464714f1ab	HAL_PX4: fixed build warning	10 years ago
Andrew Tridgell	0c73dc2440	HAL_PX4: use common RingBuffer.h	10 years ago
Matthias Badaire	1d3a49e466	AP_HAL_PX4 : make UARTDriver capable to be called from different threads. The modification allows the read and write functions to be called by any thread but the calling thread must be the last one that called the begin() function.	10 years ago
Andrew Tridgell	10b0ca7ea8	HAL_PX4: reduce the number of times we split up UART reads and writes	10 years ago
Andrew Tridgell	48247b6adc	HAL_PX4: minimise usage of hrt_absolute_time()	11 years ago
Andrew Tridgell	0a20d0db60	HAL_PX4: prevent read past end of buffer	11 years ago
Andrew Tridgell	a7d6a26bec	HAL_PX4: fixed auto-flow control the 6 bytes written to break the radio out of bootloader broke auto flowcontrol detection	11 years ago
Andrew Tridgell	4e2e685d7a	HAL_PX4: better fix for IFLOW on all ports the tcsetattr() call fails to apply the baudrate if the port has no RTS pin and we ask for IFLOW. So just make a separate call.	11 years ago
Andrew Tridgell	b2cdd39a99	HAL_PX4: don't enable IFLOW on ports without flow control this should have been harmless, but breaks the GPS on Pixhawk. This disables it until we work out why.	11 years ago
Andrew Tridgell	c5c1d1358a	HAL_PX4: added automatic hardware flow control detection this allows us to detect if hardware flow control is not available and automatically disable it	11 years ago
Andrew Tridgell	3e637ac5d9	AP_HAL: added enable_flow_control() option in AP_HAL	11 years ago
Andrew Tridgell	a95868e124	HAL_PX4: even larger tx buffer size for faster log transfer	11 years ago
Andrew Tridgell	ff7004fcc5	HAL_PX4: use larger buffers on USB	11 years ago

Andrew Tridgell	e34cc6dd9a	HAL_PX4: added some UART debugging this may help to track down USB issues	11 years ago
Andrew Tridgell	ad30f8effa	HAL_PX4: try to reopen UARTs if safety switch is disarmed this allows attaching to the USB port after power on Pair-Programmed-With: Randy Mackay <rmackay9@yahoo.com>	12 years ago
Andrew Tridgell	7067569103	HAL_PX4: fixed end() on UARTs	12 years ago
Andrew Tridgell	40af9ab674	AP_HAL_PX4: updates for new API	12 years ago
Andrew Tridgell	05b426c1fc	HAL_PX4: use common printf implementation on UARTs	12 years ago
Andrew Tridgell	2340bb6220	PX4: use a minimum transmit buffer for UARTs of 512 bytes this avoids writes stalling on the GPS port. We can't afford this memory on APM2, but we can on PX4, and it means that while the GPS is blocking at startup it doesn't cause any scheduler slips	12 years ago
Andrew Tridgell	0916388ab5	HAL_PX4: retry opening UARTs up to 5 times this seems to help a lot with the USB port on PX4	12 years ago
Andrew Tridgell	8766e86091	HAL_PX4: fixed blocking bulk writes to UARTs this fixes a problem with uBlox initialisation on PX4	12 years ago
Andrew Tridgell	14911eff6c	HAL_PX4: added a (disabled) trick for handling blocking ttyACM0 this doesn't work yet, but is worth having for debugging	12 years ago
Andrew Tridgell	c373429a6e	HAL_PX4: fixed a buffer handling bug BUF_SPACE() was badly buggy, which could lead to memory corruption	12 years ago
Andrew Tridgell	54e7bce75e	HAL_PX4: cope with O_NONBLOCK not working in NuttX on ttyACM0 writes will block anyway, which clags up APM	12 years ago
Andrew Tridgell	fc8065b50f	HAL_PX4: added UART performance counters	12 years ago
Andrew Tridgell	f72b532405	HAL_PX4: ensure all writes go via buffers this prevents output corruption by direct fd writes	12 years ago
Andrew Tridgell	89cb3fbd61	HAL_PX4: fixed blocking IO in UART driver	12 years ago
Andrew Tridgell	6ffa18fa61	HAL_PX4: rewrite UART driver to be much more efficient this does the IO in the timer thread, and uses buffers in the main task to avoid system call costs in the flight code. The cost of PX4 read and write system calls is quite high - about 10 to 15 usec. We can't afford to pay that per byte	12 years ago
Andrew Tridgell	546ed19ffc	HAL_PX4: improved efficiency of serial writes use buffer at a time writes when possible, and use O_NONBLOCKING to avoid txspace()	12 years ago
Andrew Tridgell	18cfd29f2f	HAL_PX4: added a read buffer to the UART driver this lowers the average cost of reading bytes by a large amount, and prevents the GPS driver from chewing lots of time.	12 years ago
Andrew Tridgell	76092eb590	AP_HAL: remove unused peek() interface from UART drivers this is a bit tricky to implement on some platforms, and is unused anyway	12 years ago
Andrew Tridgell	64a8a8e4c9	HAL_PX4: fixed using mavlink on the console this disables the ONLCR termios flag, which was injecting extra carriage returns in the output	12 years ago
Andrew Tridgell	30447018d5	HAL_PX4: handle %S in format strings	12 years ago
Andrew Tridgell	08d518e07f	HAL_PX4: switch to libc vdprintf() vdprintf has now been added to NuttX	12 years ago

Andrew Tridgell	155fca8a4b	HAL_PX4: make APM sketches into daemons this also moves uartA onto UART5, allowing ttyS0 for nsh	12 years ago
Andrew Tridgell	d492b72a2c	HAL_PX4: use /dev/ttyS0 for uartA this also changes txspace and available to use FIONWRITE and FIONREAD	12 years ago
Andrew Tridgell	c6c336a6e8	HAL_PX4: implement peek() and available() keep a 1 byte buffer	12 years ago
Andrew Tridgell	d9d5eb52bf	HAL_PX4: use fd IO instead of stdio this allows for hal console output from within timers, which is very handy for debugging	12 years ago
Andrew Tridgell	9373a4e5b3	HAL_PX4: added a uartA driver uses stdin/stdout for IO	12 years ago
